Google Play Billing v8

Symptoms

After migrating to Google Play Billing 8.x, some apps may experience that prices are not displayed in Purchasely Screens.

In this situation:

• the SDK initialization fails to retrieve the Google Subscriptions.y
• the blocking call is typically queryProductDetails() (Google products fetch)

This prevents all In-App Purchase features from working with Purchasely

Root cause (likely)

This issue can happen when the project includes the dependency:

• com.android.billingclient:billing (non-KTX)

while the Purchasely SDK relies on:

• com.android.billingclient:billing-ktx.

⚠️ Requirements for these fixes

Two conditions are necessary. Both are independent of your own code.

1. Purchasely SDK 5.4.0 or later

Purchasely SDK 5.3.x and earlier call enablePendingPurchases() without an argument. Google Play Billing 8 removed this method. The build gives no error. At run time the SDK throws a NoSuchMethodError, the BillingClient never connects, and the Screens show no prices.

2. A Kotlin 2.1 compiler or later in your project

Google Play Billing 8 is compiled with Kotlin metadata 2.2, and it brings kotlin-stdlib 2.2. A Kotlin 2.0 compiler refuses these artifacts:

Module was compiled with an incompatible version of Kotlin.
The binary version of its metadata is 2.2.0, expected version is 2.0.0.

This second condition comes from Google Play Billing. No Purchasely version removes it. If your project is on Kotlin 2.0, for example a React Native project before version 0.79, move your project to Kotlin 2.1 or later first.

✅ Fix #1 — Use billing-ktx (recommended)

Make sure your app uses the Kotlin variant of Google Play Billing:

dependencies {
    implementation("com.android.billingclient:billing-ktx:8.3.0")
}

✅ Fix #2 — Force Gradle resolution to Billing v8 (workaround)

If another dependency forces billing (non-KTX), you can force dependency resolution to ensure both artifacts are aligned:

configurations.all {
    resolutionStrategy {
        force("com.android.billingclient:billing:8.3.0")
        force("com.android.billingclient:billing-ktx:8.3.0")
    }
}

• Purchasely SDK version
• Google Play Billing version
